Title (EN) METAL HALIDE LAMP
(FR) LAMPE A HALOGENURE METALLIQUE
(JA) メタルハライドランプ
Abstract: front page image
(EN)Disclosed is a metal halide lamp which comprises a ceramic arc tube and a pair of electrodes arranged opposite to each other. This lamp contains a Pr (praseodymium) halide, an Na (sodium) halide and a Ca (calcium) halide filled in the arc tube. The amount of praseodymium halide filled in the tube (Hp [mol]), the amount of sodium halide filled in the tube (Hn [mol]), and the amount of calcium halide filled in the tube (Hc [mol]) satisfy the following relations: 0.4 ≤ Hc/Hp ≤ 15.0 and 3.0 ≤ Hn/Hp ≤ 25.0.
(FR)L'invention concerne une lampe à halogénure métallique qui comprend un tube à arc céramique et une paire d'électrodes montées de manière opposée l'une par rapport à l'autre. Cette lampe contient de l'halogénure de praséodyme (Pr), de l'halogénure de sodium (Na), de l'halogénure de calcium (Ca) remplis dans le tube à arc. Les quantités d'halogénure de praséodyme dans le tube (Hp[mol]), d'halogénure de sodium dans le tube (Hn[mol]), et d'halogénure de calcium dans le tube (Hc[mol]) satisfont les équations suivantes : 0,4 = Hc/Hp = 15,0 et 3,0 = Hn/Hp = 25,0.
(JA) 本発明のメタルハライドランプは、セラミックから形成された発光管と、一対の対向する電極とを備えている。このランプは、発光管の内部に封入されたPr(プラセオジム)のハロゲン化物、Na(ナトリウム)のハロゲン化物、およびCa(カルシウム)のハロゲン化物を有しており、Prのハロゲン化物の封入量Hp[mol]、Naのハロゲン化物の封入量Hn[mol]、およびCaのハロゲン化物の封入量Hc[mol]が、0.4≦Hc/Hp≦15.0、および3.0≦Hn/Hp≦25.0の関係を満たす。
